Abstract
In this study, we confirm the possibility of applying stretch-fabrication on models with various shapes to allow technological establishment of such tensile film membrane structures, and shows through validation tests that this approach can be applied to actual structures. First, the applicability of stretch-fabrication is confirmed by introducing tension for study models with various shapes. Also, through validation tests, the effectiveness of the stretch-fabrication method using an arch and the viscous behavior of the film after stretch-fabrication is investigated. Additionally, the elasto-plastic analysis is carried out by considering the viscous behavior of film, and the validity of the analysis results is examined by comparing to experimental results. After stretchfabrication, the mechanical behavior of the film is also investigated.
